When adding a new board, it can be non-obvious what went wrong if the
board is not immediately detected. Add an option to trace through
socinfo addresses for a specific board to print out useful addresses
as a debugging aid. Also clean up some error handling, mostly among
the tracing code.

The specification of boards of the parser is not very clean. Re-write
it into an easier to read fashion.

After a crash, ramdumps may be collected for analysis. The ram
parser is a tool to aid in analysis of these dumps. The script
extracts useful information from the dumps to help with debugging.
Please see the README for full details.
